To all whom 'it may concern:

Be it known that 1, FRANKLIN L. LANE, a citizen of the United States, residing at Beloit, in the county of Rock and State of isconsin, have invented certain new and useful mprovements in Matcher-Heads, of which the following is a specification.

The invention has to do with the provision of an improved form of duplex tool head of the general type shown in Patent 1,036,862, issued to me onAugust 27, 1912, wherein each component partV of the head has tools arranged radially about its periphery, the tools of the respective parts interiitted in such manner as to act in succession on the stock.`

The invention also concerns the provision of improved means for clamping the head on the shaft.

1n order that the invention may v be readily understood by those skilled in the art, 1 have in the accompanying drawings and in the following detailed description predicated thereon set forth a preferred embodiment of the invention. As obviously the invention may be embodied in other varied and constructionalforms without departure from the essence thereof or sacrifice of its material advantages, it is to be understood that the description and drawing are to be taken in an illustrative and not in an unnecessarily limiting sense.

1n the drawings Figure 1 is a side elevation of a matcher head yembodying the invention; Fig. 2 is an end elevation of the same; Fig. 3 is a longitudinal section through Fig. 1; Fig. 4 is a similar section taken upon a different line; and Fig. 5 is a transverse section on the line 5-5 of *ist 3.

The matcher head illustrated in the draw* ings is really made up of two head members, one of these indicated at 11, having a tubular hub 12, the bore 13- of which is provided at each end with a beveled approach 14 and 15 respectively. The head 11 has projecting therefrom radial ,arms 11a having secured thereon in any suitable manner tools 16. As here illustrated the tools are secured in position by means of clamps 17 having lips 18 engaging' over the tool 16 and another lip 19 engaging the beveled surface 2O of the arm of the tool head, the being drawn together .by

means of the nut 21 on the bolt 22 which passes through the arm and into engage ment with both of the clamps. The other tool head 23 has likewise a tubular hub 24 but the interior of the hub 24 is cylindrical instead of having beveled approaches as in the other case. The hub 23 has similar radial projections 23a provided with tools as in the case of the projections 11a, the arms 23 and their tools lying in the spaces between the arms 11EL and the tools16 and bearing'laterally thereon to prevent angular displacement.

1t will be readily understood that the tools 16 carried by the arms of the respective tool heads 11 and 23 act in succession upon the stock. In the drawing these tools are represented as groove forming tools and they are arranged alternately at different slight angles to the plane of rotation. 1t will thus be seen that each of the tools forms a clearance for the following tool. The cutting edge 16a (Fig. 1) cuts the bottom and one side of the groove while the succeeding tool 16b cuts the bottom and the opposite side of the groove. 1n order to Shift the position of the groove or tongue upon the stock or to cut a wider or narrower groove, it is only necessary to Shift axially one ofthe sets of cutting edges 16al or 16b with reference to the other set. This is done by `shifting that head member which carries the cutting edges 16a and that head member which carries the cutting edges 1Gb a greater or less distance. 1 provide improved means for adjusting these members axially in the manner following: The hubs 12 andl 241 of the heads 11 and 23 respectively are telescopically arranged, the hub 12 snugly fitting within the hub 21. The former'extends beyond the end of the latter and the end portions of each are screw threaded as indicated at 25 land 26, respectively, the threads 25 being of coarser pitch than the threads 26. An adjusting nut 27 has a threaded portion 28 in engagement with the thread 25 of the hub 12 and an other portion 29 having threads in engagement with the threads 26 of the hub 24:. The threaded portion 25 of the hub 12 is provided with a lock nut 30 adapted to bear against the upper end of the adjusting nut 27 and the threads 26 of the hub 24 are likewise engaged by a lock nut 31 adapted to bear against the opposite end of the adjusting nut 29.

It will be readily understood that the concentric hubs 12 and 24 of the two component head members having been slipped one upon the other in telescopic relation with the projecting arms 11a and 231 and their tools interfitted, and the adjusting nut 27 having been brought into position with its threads engaging the threads 25 and 26 of the hubs 12 and 24, the rotation of the adjusting nut 27 will, by reason of the different pitch of the threads 25 and 26, cause the hub 23 to move in one direction and the head 11 to move in the same direction but at a different rate of speed, whereby the relative location of the tool heads will be axially adjusted.

In order to provide for the fixed adjusted mounting of the duplex cutter head upon the end of the shaft 32 the following provision is made: About the shaft 32 and within the central bore of the hub 12 is disposed a sleeve 33 which is cup-shaped and has its open end enlarged as indicated at 34 and provided with an exterior beveled face 35 adapted to coperate with the i beveled face 14 on the approach to the bore 15 of the hub. The side walls of the sleeve 33 are longitudinally slotted to lend resilience in order that the same may expand and contract, and the closed end of the sleeve which is cup-shaped is provided with a central aperture interiorly threaded as indicated at 36. At the opposite end of the bore 13 is arranged another cup-shaped sleeve 37 the walls of which are longitudinally slotted and exteriorly beveled at their open end as indicated at 38 for coperation with the beveled approach 15 to said bore.

The closed end of this cup Sleeve is likewise provided with an axial aperture 39 interiorly threaded, the threads of the aperture 39 having a dierent pitch from those of the aperture 36.

The relative axial movement of the sleeves 33 and 37 whereby their beveled ends 3S and 35 are caused to act upon the beveled faces 14 and 15 of the approaches of the bore 13, is effected by means/of a duplex screw. This duplex screw comprises a tubular screw member 40 having threaded portions 41 and 42 of different diameter and pitch for engaging within the threaded portions 36 and 39 of the two sleeves, such tubular screw 40 being rotated by means of its polygonal head. The tubular screw 40 is axially bored and interiorly threaded and has seated therein a second screw member 43 provided with a polygonal head 44 and having an inner end 45 projecting beyond the tubular screw 40 into engagement with the end of the shaft 32. Upon the inner screw member 43 is mounted a lock nut 46 which is adapted to bear upon the head of the tubular screw 40. A stud 47 seated within the enlarged end 34 of the sleeve 33 takes into a groove formed in the end of the hub 12 so as to prevent relative rotation of the sleeve and hub. Similarly a stud 48 seated in the bottom of the cup-shaped sleeve 37 takes into an aperture 49 in the bottom of the cup-like sleeve 43 whereby the two sleeves 33 and 37 are locked against relative rotation while permitting freely of longitudinal or axial movement.

rlfhe two sleeves having been arranged in telescopic relation within the hub 12 with their beveled faces bearing against thebeveled approaches to the bore of the hub 12 and with the bottom portions of the sleeve 33 envel oped by the bottom portion of the sleeve 37, the tubular screw 40 is inserted within the threaded aperture 36 and 39 and, the lock nut 46 having been loosened the screw 43 is so adjusted within the tubular screw 40 as to properly position the cutter head upon the shaft 32. This adjustment having been secured the tubular screw 40 is manipulated by means of its head so as to move the sleeve 33 in one direction and the sleeve 37 in the opposite direction, thereby causing the beveled faces on the two sleeves to ride upon the beveled approaches of the bore and contract the inner sleeve 33 upon the shaft 32. rlhereupon the lock nut 46 is screwed home against the head of the tubular screw 40 and the permanency of the mounting of the head upon the shaft is secured.

I claim:
